Thick vibrating screen 25 is consistent with the structure of thin vibrating screen 26, the difference is that the aperture of sieve pore is different on sieve plate.Such as Shown in Fig. 2 to Fig. 6, thick vibrating screen 25 or thin vibrating screen 26 include pedestal 1, are equipped with damping device and screen box, this reality on pedestal 1 Applying damping device in example is the damping spring 23 being packed on pedestal 1, damping spring upper end and the support for being packed in screen box side It manages affixed, sieve plate 2 is installed in screen box, screen box discharge end corresponds to sieve plate and is respectively equipped with the first discharge port 3 and the second discharge port 4, Screen box bottom is fixed with force transmitting board 21, and the bottom of force transmitting board 21 is fixed with vibrating motor 5, and the top of screen box is equipped with screen cover 6, screen cover 6 two sides are fixed with handle 20 respectively, and screen cover 6 can grasp handle 20 when dismantling, convenient for moving screen cover 6.

The feed end of screen cover 6 is equipped with feed inlet 7, and screen box is enclosed by the two blocks of side plates 8, charging end plate 9, bottom plate 10 being oppositely arranged At side plate 8, the top for feeding end plate 9 are connected with the lower connecting ear 11 of overhanging setting, correspond to lower connecting ear 11 in screen cover 6 and are equipped with Upper connecting ear 12, by worn in the corresponding bolt hole opened up of upper connecting ear 12 and lower connecting ear 11 bolt realize screen cover 6 with The fixation of screen box.The weight of material is subject due to side plate 8 and the exciting force that vibrating motor 5 generates is transmitted to sieve plate 2, this reality It is connected with the stiffening plate 22 that muti-piece is connected as one in the bottom in the outside of two blocks of side plates 8 and bottom plate 10 in novel, is passed through The setting of stiffening plate 22 can enhance the rigidity of side plate 8.

Recessed formation cushion cap, the both sides of sieve plate 2 are respectively placed on corresponding cushion cap, hold from top to bottom for the inside of side plate 8 The top of platform is equipped with the briquetting 13 for being pressed sieve plate 2, and screen cover 6 and screen box fix the top surface of rear briquetting 13 and the bottom of screen cover 6 Face paste is closed, and the outside spacers of briquetting 13 are equipped with the muti-piece limited block 14 vertically arranged along briquetting 13, and the cross section of limited block 14 is in The width of dovetail shaped, that is, limited block 14 is laterally gradually reduced with 13 connecting side of briquetting by outer, and the limited block 14 of such structure is using In the process will not transverse shifting, guarantee limited block 14 position accuracy, and then guarantee even if briquetting 13 under vibration Firmly sieve plate 2 can be compressed, the inside of side plate 8 corresponds to limited block 14 and is equipped with the card slot being from top to bottom inserted into for limited block 14. In the utility model the length of limited block 14 be greater than the distance between cushion cap upper surface and 8 upper surface of side plate, the depth of card slot and The length of limited block 14 is consistent, and the length of limited block 14 is greater than the length of briquetting 13, and the stability after briquetting 13 is installed can be improved.

Since the fixed firmness of sieve plate 2 has a great impact to mud separation, wanted to meet the intensity of the installation of sieve plate 2 It asks, briquetting 13 must have stable state.The stability installed in the utility model for enhancing briquetting 13, the top of briquetting 13 It is connected with the extension block 15 of overhanging setting, the top surface of extension block 15 and the either flush of briquetting 13, the setting of extension block 15 can increase Big screen cover 6 enhances the stability of briquetting 13 to the pressurization area of briquetting 13, the top of side plate 8 correspond to extension block 15 equipped with for The deep gouge that extension block 15 is caught in.To be easy to disassemble, the inside of briquetting 13 is equipped with the notch 16 for hooking handgrip, and sieve plate 2 is replaced When, handgrip can be caught in notch 16, briquetting 13 and limited block 14 can be taken out by then above mentioning, and improve the side that briquetting 13 is dismantled Just property.

It is connected on charging end plate 9 to guarantee that the mud on sieve plate 2 is evenly distributed, in the utility model flat with sieve plate 2 The width of the charging bearing plate 17 of row setting, charging bearing plate 17 and screen box is adapted, and charging bearing plate 17 is corresponding with feed inlet 7 Setting, the upper surface of charging bearing plate 17, which is dissipated centered on the projection on charging bearing plate 17 equipped with muti-piece by feed inlet 7, to be set The split-flow baffles 18 set, split-flow baffles 18 are arranged perpendicular to charging bearing plate 17, correspond on sieve plate 2 split-flow baffles 18 be equipped with edge into Sieve plate 2 is divided into multiple screening areas by the demarcation plate 19 of discharging direction setting, demarcation plate 19.Mud enters screen box from feed inlet 7, It falls on charging bearing plate 17, due to the split-flow baffles 18 of diverging setting, mud slurry uniform branches to corresponding screening area and along sieve Plate 2 is mobile to discharge port.It due to the setting of split-flow baffles 18 and demarcation plate 19, can prevent mud from assembling at the one of sieve plate 2, increase The separative efficiency of strong mud.Due to charging bearing plate protrusion charging end plate setting, to be taken out from screen box convenient for sieve plate, sieve plate Length is less than the length of side plate, is advisable with can just accept the mud flowed down from sizing material bearing plate, when taking-up only need by Sieve plate inclination can avoid charging bearing plate and smoothly take out.

Sieve plate 2 is pressed by briquetting 13 in the utility model, and due to the setting of limited block 14, briquetting 13 is in use Transverse shakiness will not occur, due to being pressed while screen cover 6 and fixed screen box bolt to the length direction of briquetting 13, guarantee Briquetting 13 will not be vertically movable, to guarantee the fixed firmness of sieve plate 2.When sieve plate 2 needs repairing or replaces, only need to open Screen cover 6 takes out briquetting 13, and structure is simple, and installation, maintenance is convenient.

When the present apparatus works, mud is delivered to the feed inlet of thick vibrating screen 25 through pumping, and thick vibrating screen 25 sieves mud Point, the solid phase of bulky grain can be discharged, and remaining mud enters storage slurry case 27, and the slurry transportation in slurry case 27 will be stored by flowing stock pump 30 at this time To cyclone 28, after cyclonic separation, slurries up to standard flow out simultaneously from the overflow port of cyclone 28 after most purification separations Into in slurry-storing box 29, the circulatory system of drilling fluid is returned, the waste residue that cyclone 28 is isolated then passes through its discharge port and drains into carefully In vibrating screen 26, thin vibrating screen 26 is dehydrated waste residue and finally excludes.

The above is only the preferred embodiment of the present invention, is not intended to limit the utility model.Previous embodiment The utility model is described in detail, it for those skilled in the art, still can be to aforementioned each implementation Technical solution documented by example is modified or equivalent replacement of some of the technical features.In every case practical new at this Within the scope of the inventive concept of type, any modification, equivalent substitution, improvement and etc. done are all contained in the protection of the utility model Within the scope of.
